“…Moreover, this method is mentioned in seismic provisions for Structural Steel Buildings (AISC 2005) in chapter 17 [13]. The second model is based on the plastic yielding of the plate with surrounding frame (plastic yielding model) presented by Sabouri & Roberts (1991) [10]. In this study the first model is employed to design steel shear walls.…”

When an earthquake occurs, the structure will enter into a nonlinear stage; therefore, new approaches based on nonlinear analysis are needed to flourish with the purpose of more realistic investigations on seismic behavior and destruction mechanism of structures. According to the modern philosophy, "Performance-based Earthquake Engineering" is formed in which simple nonlinear static analyses are mostly used in order to determine the structure's behavior in nonlinear stage. This method assumes that the structure response is only controlled by the main mode and the shape of this mode will remain the same, while it enters the nonlinear stage. Both of these assumptions are approximations, especially in high buildings, which have a long period. It seems that constant load pattern used in these methods cannot consider all of the effects properly. In this paper, an attempt was made to study the accuracy of these methods in comparison to nonlinear dynamic analysis, by considering various load patterns existing in FEMA, also load patterns proportional to higher modes in nonlinear static method, and employing an approximative method of MPA modal analysis, study the accuracy of these methods in comparison to nonlinear dynamic analysis. For this purpose, three steel frames of 4, 8, and 12-stories with steel shear wall have been studied.

“…On the basis of existing analytic simplified formulations [12,13], the panel dimensions have been determined as b = 600 mm, d = 2400 mm and s = 1.15 mm. In order to guarantee a b/d ratio lower than 0.8, that is indicated as the lower bound of the aspect ratio beyond which the development of a correct plastic mechanism is not developed, the insertion of appropriate transversal rectangular stiffeners (height of 100 mm and thickness of 4 mm) along the whole panel length has been foreseen.…”

“…(1), which would allow using a column depth equal to 1/2 of the actual one, has been determined considering the columns as supported on three points. In such a way the bending moment applied to the vertical elements is equal to 1/4 of the one characterising the scheme without the intermediate member [12], thus determining smaller dimensions of the columns. On the other hand, the beams have to be characterised by an adequate flexural stiffness and strength to allow an uniform tension field in the shear panel surface.…”

ABSTRACT:In the present paper the seismic upgrading of an existing RC structure by using slender steel shear panels is examined. Based on a preliminarily experimental evaluation of the performance of the bare RC structure, an ad hoc design procedure has been developed in the framework of the performance based design methodology. The applied device, whose configuration has been defined also according to both simplified and refined numerical analyses, is able to significantly enhance both the strength and the stiffness of the primary structure. It has been installed within a reaction steel frame, positioned into the bare RC structure, which is composed by members designed in order to remain in elastic regimen under the tension field action developed by plates. Since the original RC module was not able to withstand significant values of horizontal forces, the reinforcing of both the first level beam and the foundation beam by means of coupled channel steel profiles and threaded bars has been done. Finally, in order to assess the reliability of the proposed intervention, a full scale cyclic experimental test has been performed on the upgraded structure, confirming the effectiveness of the adopted technique as well as the validity of the proposed design procedure.Keywords: Slender steel shear panels, seismic upgrading, GLD building, experimental test, tension field mechanism, plate buckling INTRODUCTIONIn the framework of new seismic design approaches for upgrading existing reinforced concrete buildings, the development of innovative intervention techniques, based on either the reinforcement of existing structural elements or the introduction of new resisting systems, the metal-based technology approach can be considered very profitable [1]. Such a technique is founded on the energy dissipation capacity of special metallic devices able to achieve or improve the structural safety of the original structure under seismic actions.Within this category, the solution based on using metal shear panels can result particularly effective, due to the limited weight, the reduced volume obstruction, the easy insertion and the meaningful structural contribution offered by the applied devices in terms of strength, stiffness and ductility. In addition, it is important to observe that the self-weight of steel panels is rather low, if compared with the one of a reinforced concrete shear wall, determining in this way a reduction of gravitational loads and therefore of seismic actions transmitted to the foundation.Nowadays, metal shear panels adopted in seismic applications can be subdivided in two main behavioural classes: 1) the so-called "compact" panels, mainly made of low strength metallic materials (LYS steel or pure aluminium) and properly stiffened in order to avoid elastic shear buckling phenomena, which have been recently proposed for high steel buildings and also for reinforcement of RC buildings [2]; 2) the "slender" shear panels, made of thin steel plates, which have been widely studied and applied both in North America and ...

“…They consist of thin at steel plates referred to as in ll panels which are framed by beams and columns [3][4][5][6]. The experimental and analytical studies on the thin SPSWs have been performed under monotonic and cyclic loading [7][8][9][10][11][12][13][14][15][16][17]. The surrounding steel frame can be applied with either simple or moment-resisting beam-to-column connections.…”

Abstract. Structural engineers have recognized unsti ened Steel Plate Shear Wall (SPSW) as an economical lateral resisting system due to the post-buckling capacity, energy dissipation, and deformability. This study investigates practical application of an added Energy Absorbent Element (EAE), subjoined to the SPSW in order to improve seismic behavior of the SPSW. The EAE is an aluminum shear panel with or without bracings and surrounding frame. Furthermore, a series of parametric studies are implemented to examine the e ect of dimensions, position, and formation of the EAE. It is assumed that the lateral loading is applied as quasi-static loading. Further, nonlinearity of the material and the geometry are included in the models. The results reveal that by adding the EAE adjacent to the surrounding frame of the SPSW, not only dissipated energy, but also ultimate strength of the system can be e ciently increased.
